We are a third grade classroom and we have been incubating 11 eggs. They started hatching yesterday. One of the chicks was born with an exposed yolk sack. We left in the incubator over night and most of the yolk has been abosrbed. However, there is still a pea sized part hanging out. Is there anything we should be doing that will help this chick out. We have 4 other healthy chicks and one that has started pipping. Thank you for any help you could give us.
